Hi,
Couple of patches that convert the MIPSfpga platform to using
the generic kernels
Based on v4.11-rc4.
Regards,
ZubairLK

Thanks, Applied for 4.15.
Tweaks to fix conflicts:
- Use separate board-xilfpga.its.S.
- Add 32r2 and little endian requires to board-xilfpga.config
- Update arch/mips/Makefile snippet and move to end
Cheers
